Learning unit contents

This course deals with the chemistry of renewablee resources from fundamentals concepts to technical and industrial applications
Chapter 1. Chemistry of renewable resources: context of this course and up-to-date examples - classification and definition - renewable vs. non renewable resources 
Chapter 2-4: basic concepts - chemistry of water and gas (CO2, O2 and N2)
Chapter 5. Carbohydrates : classification of carbohydrates, principal sugars and nomenclature, structure and conformation, chemical reactivity and physical properties, polysaccharides, applications.
Chapter 6. Lipids : nomenclature, chemical structure and physico-chemical properties, glycerides, unsaponifiable, application domains.
Chapter 7. Amino acids, peptides and proteins. Structure and principal properties. Exemple of protein structures (alpha-keratin, fibroïn, collagen, elastin). Protein denaturation mechanism and practical importance. Amino acids, peptides and proteins : Analysis, sequence, conformation, peptide synthesis, interactions, modifications, purification. Structure activitiy of proteins. Biomolecules analysis and purification methods.
Chapter 8. Secondary metabolites (polyphenols, terpens, alkaloids) 

Learning outcomes of the learning unit

To give basic knowledge in organic chemistry of natural molecules. To draw molecular and structural properties of biomolecules.Present analysis and purification methods for biomolecules. After completing the course the student is expected to be able to give back the basic knowledge of the three main groups of compounds from biological origin : protein, lipids and glucids, to demonstrate the convergence points with the cursus in organic chemistry and to point out the first applications of the teached topics.Understand the different principles of bio-molecules separation and be able to choose the right principle in function of the molecules to separate Understand the ionization phenomenon and predict the possible effect on association, biological activity.
